Congratulations! As the owner of this state-of-the-art EnTire Solution Tyre Pressure Monitoring System
(TPMS), you will enjoy the improved convenience and benefits of having tyre pressure information automatically
monitored while you are driving!
EnTire Solution Tyre Pressure Monitoring System (TPMS) consists of sensors installed on valve stems and a
LCD display monitor mounted in the cab. The sensor monitors tyre pressure and temperature inside the tyre
and transmits the information wirelessly to the LCD monitor. The device can give real time warning of tyre leak,
minimizing the chance of serious damage like tyre blowout to ensure driving safety.
In order for EnTire Solution Tyre Pressure Monitoring System (TPMS) to work properly, please follow the
installation instructions carefully.

EnTire Solution Tyre Pressure Monitoring System is designed to identify and display tyre operating status and
activate an alert when a pressure or temperature irregularity is detected (i.e. higher or lower than standard tyre
pressure and higher than default tyre high temperature setting).
EnTire Solution TPMS and Driving Safety
It is driver’s responsibility to react promptly and properly to the alerts. Abnormal tyre pressure should
be corrected at the earliest opportunity to ensure driving safety.
'IMPORTANT. The presence of a TPMS system does not remove the necessity to make
regular tyre pressure checks.'
EnTire Solution TPMS Installation and Usage
EnTire Solution TPMS system user must install and set up the system strictly following instructions of this
user manual.
Standard tyre pressure value, as recommended by tyre manufacturer, needs to be put into the system first
before the system can work properly. Refer to your vehicle owner’s manual for your tyre’s standard pressure
value.
The recommended and factory preset threshold value for high temperature alarm is 176°F (80°C).
This system works on a variety types of vehicles with maximum cold tyre pressure of 9 bar or 130 psi.
Please note that the senor's weight (~0.63 Oz, 18.0±1 grams) may affect the tyre‘s balance after installation. It
is recommended that a user to have the tyre balance checked at a tyre installation centre.
